- It may be that the recess having an enlargement 'tom of the head 30 and located beneath the shaft to hold the stem in the head. A threaded on the lower end of the stem 34 and inwardly of the nut 36, the stem is surrounded by a compression spring 37. There may be washers 38 on the stem 34, at the ends of the spring 37.

In practical operation, the "Bendix drive is inserted transversely into the pedestal 15, through the openings 18 and 19, the screw ing 18 and the pinion '7 being received in the recess 16. y The screw isadvanced to hold the screw shaft 1 against movement, the screw shaft having lirstbeen adjusted vertically, sleeve 4 will be disposed oppositeto the creasing disk 27. The stem 34 is thrust downwardly through the hollow screw shaft 1, tlie'ribs 33 on the head 30 of the rotator 29 being received inthenotches or seats 6 which are formed in the upper end of the sleeve 4. The spring 37 and the washers 38 are mounted onthe lower endof the stem 34, and the nut 36 i'siappliedand advanced along the stem to compress the spring 37, therebyuholding the ribs 33 ofthe head 30 of the rotator 20 in the seats 6 of the sleeve 4. Through the instrumentality' of the feed screw24 the slide 25 is advanced, bringing the creasing disk 27 against the periphery of the sleeve 4. Bymeans of th'e'handle 31, the head30 will be rotated, and rotation will be imparted to the sleeve 4, because the ribs 33 of the head are engaged in the seats 6 of the sleeve. When thesleeve 4 is rotated andwhen the slide is advanced, the creasing disk 27 will form' the crease5 in the sleeve 4'and connect the sleeve 4 to the hub E2 of the screw shaft 1.

In Fig. 3 of the drawings, parts hereinbefore described have been designated by numerals previously used, with the suffix a way through the screw shaft '1, longitudinally'thereof. Then, ohviously,such a part as the long stem 34 ofeFig. 1 cannot be used, recourse being had to the short stem 40 41 engaging the bothandle 3-1. The stem 40 has a reduced neck providedwith an enlargement 43 received in the recess 39 of the screw shaft 1 the enlargement 43 including a conical portion adapted to he engaged by a screw 45 the screw being threaded into the opening 3 of the hub 95 of the screw shaft 1 the parts 33 and 6 of Fig. 1 operating, ashereinbefore explained, to connect, the head with the sleeve, to secure a rotation ofthe sleeve.

Let it be supposed that it is desired to place thecounterweight-8 on the pinion7.

nut 36 is 1 being received in the notch or opening upon the diameter so that the proper portion of the 3.9 extends but part The first step incident to such a proceeding is to remove the pinion 7 from the screw clamp blocks 46 are brought together, the

nut 11 may be held in the 'co-operting notches 48 of the blocks inthe cooperating notches 4? or in the cooperating notches 49, dependof the nut 11, the lllOCkS 46 being held together in revise or in any other suitable device. The rotator,

whether provided with the stem 40 of vFig. 3

or the stem 34 of Fig. 1, is inverted frointhe positions shown in those figures, the handle 31 or 31 being received in the seats or notch 6 of the sleeve 4 and the neck of the screw being received in the seat 32 or 32, the screw 45 being mounted in the opening 3 or 3 of the screw shaft 1, as hereinbefore explained. Rotation then may be imparted to the head 1 or 1*"- and the'nut 11, being held by the clamp blocks 46may be removed. Ha ing removed the nut- 11 from the screw shaft 1, the operator threads the pinion 7 off the screw shaft-and the operation of placing the counterweight 8 on the pinion may go forward. l

The device embodies an anvil 50 made up of blocks 51 provided in their-inner edges 'with recesses 52, the blocks being provided with teeth 53. lVhen two blocks, such as those shown at 51 in Fig. 6, are placed together, the recesses 52 form of'the ribs 55 itbetweenthe inner ends of oppositely disposed lugs on the counter weight 8 and the shoulder 56 engage the upper surfaces of the lugs. The blocks 51 are" held in a vise or any other suitable machine, and when the jaws of the "vise are brought together, the plunger 54 will be advanced, the lugs on the counterweight 8 being crowded into the seats 10 on the pinion 7. r

The device as described embodies a simple means whereby many of the necessary repairs in a Bendix drive may be accomplished.

V] hat is claimed is: r

l a circular open 7 ing, adapted to receive thepinion 7 as shown In a device of the class described, a frame including pedestal having atop, there be- V ing a'recess in the pedestal, and a reduced I opening in the top,

the opening extending through the-edge of the top and the pedestal hzwing' aside opening communicating with the opening in the top, a retainer mounted in the top and in the top, a slide mounted for reciprocation on the'top, means for advancing the slide,

extending into the opening and a creaser carried by the slide and adapted to cooperate with an article which has been inserted into the opening in the top of the pedestal by way of the side opening.

' In testimony that I claim the foregoing as my own, I'havehereto afiixed my signa ture. V v
